Prefabricated components are an integral part of the prefabricated construction. One of the main challenges in seismic regions is developing constructible connections between prefabricated components that can withstand inelastic cyclic deformations. This study introduces a novel type of joint designed to connect prefabricated concrete columns and beams while effectively transferring bending moments and shear forces. To assess the seismic performance of the proposed joint, three reinforced concrete frame specimens were designed: a prefabricated concrete frame incorporating the novel joint, another using a grouted corrugated duct joint, and a third comprising a cast‐in‐place (CIP) concrete frame. Quasi‐static cyclic tests were performed on all three specimens. The results indicate that the frame utilizing the novel joints demonstrated superior seismic performance, exhibiting high drift capacity with minimal damage. These findings suggest that the novel joints are safe, reliable, and suitable for application in seismic zones.
